Value Collection 602-3030 Mechanical Depth Micrometer

Product Description

The VALUE COLLECTION 602-3030 is a mechanical depth micrometer designed for precise depth measurement in machining, fabrication, and inspection applications. It covers a measurement range of 4 inches with a graduation of 0.001 inches, making it suitable for tasks that require accurate, repeatable readings. The micrometer features a ball thimble design and a rotating rod system. It ships with 4 interchangeable rods, each with a diameter of 0.1772 inches (4.50 mm), allowing the user to cover different depth ranges within the 4-inch span. The 4-inch base length provides stable contact across wider workpiece surfaces. Machinists, toolmakers, and quality control technicians are the primary installers and users of this instrument.

The 602-3030 depth micrometer is suited for use in machine shops, toolrooms, and manufacturing environments where depth measurements of slots, holes, steps, and recesses are required. It is appropriate for both production and inspection work on metal, plastic, and similar rigid materials. The 4-inch base length makes it particularly useful on wider workpieces where a shorter base would rock or produce inconsistent readings. The rotating rod design allows quick changeover between the included rods to extend or shift the measurement range without additional tooling.

Key Features

• 4-inch total measurement range with 0.001-inch graduation for precise depth readings
• Ball thimble design for smooth, controlled advancement of the spindle
• Rotating rod system with 4 included rods for flexible range coverage
• Rod diameter of 0.1772 inches (4.50 mm) for compatibility with standard depth measurement applications
• 4-inch base length provides stable, flat contact on wider workpiece surfaces
• Mechanical operation requires no batteries or electronics

Compatibility

Designed as an OEM-style mechanical depth micrometer for general-purpose depth measurement in machine shop, toolroom, and inspection environments where a 4-inch range instrument with a 4-inch base is specified.

Installation Notes

Depth micrometers are handled and set up by machinists or metrology technicians following standard measurement practices. Before use, verify the instrument reads zero with all rods removed and the base seated flat on a reference surface. Clean the base and rod contact surfaces before each measurement to prevent debris from introducing error. Follow your shop or facility calibration schedule to maintain measurement accuracy over time.
